Al Gore on China’s climate rise: ‘I would not have seen this coming’

techcrunch.com Connie Loizos 2025-09-24 01:00:00

Twenty-five years ago, Al Gore was in the final stretch of his U.S. presidential campaign, just weeks away from an election that would ultimately slip through his fingers despite winning the popular vote. His platform included ambitious climate action, with America positioned as the natural leader of a global environmental transition. The irony of what has transpired since is not lost on him. “Looking from the standpoint of 25 years ago, I have to say no, I would not have seen this as the most

Scientists: It’s do or die time for America’s primacy exploring the Solar System

Federal funding is about to run out for 19 active space missions studying Earth's climate, exploring the Solar System, and probing mysteries of the Universe. This year's budget expires at the end of this month, and Congress must act before October 1 to avert a government shutdown. If Congress passes a budget before then, it will most likely be in the form of a continuing resolution, an extension of this year's funding levels into the first few weeks or months of fiscal year 2026.

Study Directly Links Emissions from Fossil Fuel Producers to Devastating Heatwaves

gizmodo.com Ellyn Lapointe 2025-10-01 21:14:12

A new study directly links hundreds of major heatwaves since 2000 to the emissions from fossil fuel and cement producers. Among its fundings, the researchers conclude that as many as a quarter of all heatwaves since the start of this century would have been “virtually impossible” without emissions from any of the world’s 14 largest fossil fuel and cement producers. The study, published Wednesday in the journal Nature, shows that greenhouse gas emissions from 180 of the world’s biggest cement, o

Rendezvous Robotics exits stealth with $3M to build reconfigurable space infrastructure

techcrunch.com Aria Alamalhodaei 2025-10-04 17:00:00

For decades, engineers designing space structures have been constrained by the rocket fairing: only hardware that can be folded up to fit inside can go to orbit. This makes in-space assembly time intensive and expensive. The International Space Station, the largest single object humanity has built in space, was assembled over dozens of launches and cost over $100 billion. And, of course, there is no way to modify or alter the structure once it has been assembled. Rendezvous Robotics wants to c

Not so fast: German court says Apple can’t call Watch carbon neutral

Two years ago, Apple announced its Watch Series 9 as its first carbon-neutral product. From cradle to grave, the company said the manufacturing, use, and disposal of the then-new model didn’t contribute to global warming. Now, a German court says that Apple has to recant the claim. Each aluminum Apple Watch Series 9 and Series 10 — two models with the carbon-neutral designation — generates just over 8 kilograms of carbon emissions.

Scientists Propose a Smarter Way to Hunt for Alien Radio Signals

Lightning declines over shipping lanes following regulation of sulfur emissions

As it turns out, the lightning really is responding to the ships, or rather the tiny particles they emit.

Why recycling isn’t enough to address the plastic problem

And looking into the future, emissions from plastics are only set to grow. Another estimate, from the Organisation for Economic Co-operation and Development, projects that emissions from plastics could swell from about 2 billion metric tons to 4 billion metric tons by 2060. This chart is what really strikes me and makes the conclusion of the plastic treaty talks such a disappointment.
